TIRE-HEATER.

SPECIFICATION forming part of Letters Patent No. 459,112, datedSeptember 8, 1891.

Application filed December 22, 1890. Renewed August 12, 1891. Serial No.402378. (No model.)

T0 (0% whont it may concern:

Be it known that I, JAMES H. PARKS, a citizen of the United States,residing at Clarendon, in the county of Donley and State of Texas, haveinvented a new and useful Tire- Heater, of which the following is aspecification.

This invention relates to tire-heaters, and the object of the same is toeffect improve ments thereon.

To this end the invention consists of the specific details ofconstruction hereinafter more fully described and claimed, and asillustrated in the drawings, in which- Figure 1. is a central verticalsection of my improved device. Fig. 2 is a horizontal section on theline 2 2 of Fig. 1. Fig. 3 is afront elevation of my improvedtire-heater.

Referring to the said drawings, the letter C designates a cylindricalcasing supporting the tire-box B at its upper end. This tirebox isprovided with a number of horizontal bars II, extending from front torear and upon which the tires T are supported. The rear half of the boxis closed, while the front half vis open, and doors D, of semicircularform,

close said open ends, or may be turned around to the back of the box toopen the same, whereby the tires maybe inserted into the front of thebox and moved into correct position upon the horizontal bars II withoutnecessarily lifting the tires.

The letter A designates an axis revolving at its lower end in a step Sat the center of the casing, and having a plate I, provided with atoothed ring R and with wheels IV, traveling upon a ring-shaped track K.

O is a rope or chain leading from a weight M over suitable pulleys tothe axis A, around which it is wound, and the descent of the weightcauses the rotation of the axis.

G is a regulating or governing crank whose shaft is journaled throughthe casing and carries a gear g, meshing with the rack R, and by thismeans the rotation of the axis A may be regulated by being assisted orretarded.

The letters I designate diverging arms secured to the axis, and L arelamps of any approved construction supported at the outer ends of saidarms.

U are upright-s carried by the arms, upon the upper ends of whichuprights is mounted an annular plate N, having wick-openings I just overthe burners of the said lamps, said annular plate moving beneath thebottom of the box B and below all the horizontal bars H.

In operation the lamps are lighted, the tires T placed within the boxB,and the weight M allowed to descend, whereby the arms I, carrying thelamps L, will be revolved beneath the tires, the speed of theirrevolution being regulated by the operator through the regu lating-crankG. The lamps in succession will pass any given point on the tire, andthe latter Will be slowly, uniformly, and thoroughly heated. If it bedesired to heat any particular point, all the lamps but one areextinguished, and that one allowed to stand beneath such point or movedslowly back and forth beneath it by properly manipulating the cranks.The obvious purpose of having two or more lamps 011 each arm is in orderthat tires of different sizes maybe heated without radially adjustingthe position of the lamps. The top of the box B is preferably providedwith a cover V, having exit openings or lines X for the products ofcombustion.

Other details in construction and relative arrangement of parts may bemade without affecting the fundamental principles and essentialcharacteristics of my invention.

lVhat is claimed as new is- 1. In a tire-heater, the combination, with arevolving heating apparatus, of a stationary tire box having horizontalrods extending from front to back, the front being open, and doorsclosing said open front, as and for the purpose set forth.

2. In a tire-heater, the combination, with a tire-box, of a verticalaxis mounted in bearings, diverging arms carried by said axis and havinguprights at their outer ends,an annular plate supported by said uprightsand having holes, lamps mounted on said arms below said holes, and meansfor rotating said axis, as and for the purpose set forth.

3: In a tire-heater, the combination, with a tire-box having an openbottom, of a vertical axis mounted in bearings below the center of saidbox, diverging arms on said axis carrying lamps below said open bottom,a rope wound on said axis and leading over pulleys to a weight, andgoverning devices connected with said axis, all substantially asdescribed.

4. In a tire-heater, the combination, with a tire-box having an openbottom,of a vertical axis mounted in bearings below the center of saidbox and carrying lamps moving below said open bottom, a rope wound onsaid axis and leading over said pulleys to a weight, a circular platecarried by the axis and having a toothed ring, a shaft having a gearengaging said ring, and a crank on the shaft, as and for the purpose setforth.

5. In a tire-heater, the combination, with a tire-box having an annularopening in its bottom, of a vertical axis mounted in bearings below thecenter of said box and standing at its lower end in a step, divergingarms on said axis carrying an annular plate moving below said openingand'having holes therethrough,

JAMES H. PARKS.
